A water heater thermostat is an essential component of a water heater that regulates the temperature of the water. The thermostat ensures that the water is heated to the desired temperature and maintains the temperature throughout the usage. The wiring diagram of the thermostat is crucial for proper installation and configuration of the water heater. In this article, we will discuss the 110 water heater thermostat wiring diagram for easy installation and proper functioning.
What is a water heater thermostat?
A water heater thermostat is a device that controls the temperature of the water in the tank. The thermostat works by turning off the heating element once the water reaches the set temperature and turns it back on when the temperature drops below the set point. The thermostat also regulates the high-limit temperature to ensure that the water temperature does not exceed a certain point, which can cause the water to boil and damage the tank.
The 110 water heater thermostat is a common type of thermostat used in residential water heaters. It operates on a voltage of 110 volts and is designed to work with both electric and gas water heaters.
Parts of a Water Heater Thermostat
A water heater thermostat comprises of several parts that work together to regulate the temperature of the water. These parts include:
| Part | Description |
|---|---|
| Temperature dial | A dial used to set the desired temperature of the water |
| Thermostat switch | A switch that turns the heating element on and off based on the temperature reading |
| High-limit switch | A switch that turns off the heating element when the temperature exceeds a certain limit to prevent damage to the tank |
| Reset button | A button used to reset the high-limit switch when it is tripped |
| Heating element | A component that heats the water |
Wiring Diagram for 110 Water Heater Thermostat
Wiring a thermostat for a water heater can be a bit challenging, especially if you are not familiar with the wiring diagram. The 110 water heater thermostat wiring diagram consists of two parts: the line voltage and the low voltage.
